Transmission cooler lines
 

Nubie and great to be here. I want to install a transmission cooler on my 2004 Stratus 2.7L w/automatic, but I can't determine by touching the lines which hose is the supply or return from the radiator. The 2 coolant hoses attach at the top of the radiator on the drivers side, can anyone tell me which is supply and return? Thx for the help.:cool:
